CHARLES BURTON 'WINZER, OF FULHAM, LONDON, ENGLAND, ASSIGNOR TO GEORGE BOYLE, OFLONDON, ENGLAND.

APPARATUS- FOR OPERATING PRQPELLERS FQR BOATS AND LIKE.

T auto/ 10m it may concern Be it known that I, CHARLES BURToN VVINznn, a subject of the King of Great Britain and Ireland, and resident of Fulham, in. the county of London, England, have invented anew or Improved Apparatus for @perating Propellers for Boats and the like, of which the following is a specification.

Theobject of this invention is the production of a simple and reliable apparatus for operating propellers for boats and the like, especially applicable for the boats used in large vessels in cases of wrecks or other disasters, providing a mode of moving same without the aid of skilled and trained men, so simple that any ordinary person without previous practice can perate the apparatus in an emergency without assistance from. the crew. While this is the special object of the invention, the apparatus is also most useful for pleasure boats and other similar craft, and with slight modifications, can be used for the propulsion of small vehicles and the like on land.

In order that the invention may be fully understood, reference is made to the accompanying drawings, in which:

Figure 1. is a sectional elevation of a boat showing the apparatus in action. Fig. 2. is a plan of the apparatus fitted in working position showing the mode of using by one or more operators. Fig. 3. is a plan of the apparatus. Fig. 4. is a section through line IV. IV. of Fig. 3. Fig. 5. is a section through'line V. V. of Fig. 3. Fig. 6. is a section showing a modification of the mode of fiXlll part of the apparatus for setting the course.

A hollow shaft 6 working in bearings z' 2' is fitted in boat a, and has attached to it, in a suitable position, fly-wheel f, and extension shaft h, passing through the stern of the boat and carrying a screw-propeller g at the extremity thereof. To the other end of the shaft 0 are attached casings e e. In the hollow shaft 6 an Archimedean screw a, of the necessary length, and of such a diameter. as to allow it to work freely in said shaft, operates backward and forward. In the operating end of the Archimedean screw, extensions 72 are fitted in any suitable manner terminating with a cross bar Z. for one or more persons to work the apparatus, and further extensions may be used with a Specification of Letters Patent.

greater number of operators. The Archim'ed'ean screw a is grooved in opposite directions to enable the heat to be driven ahead or astern as desired, by means of appliances now to be described.

In the casings c c are disks (Z (Z freely fitting therein, having on side eXten sions c c with notches or teeth on the edges thereof, said notches or teeth being in oppoaw,--

site directions to each other. These disks are centrally perforated to allow the Archimedean screw (6 to pass freely through, and have on their peripheries indentations d at suitable distances to allow screws (Z to fix them, or release them from casing 6. Within the casings c c are placed short hollow tubes 2; 7), working freely therein, having at one end notches or teeth in opposite directions to each other to correspond with those on the disk extensions, and facing the same, the other ends of said tubes being capped and having central orifices each shaped to correspond with and fit its particular groove on the Archimcdean screw.

In Fig. 6. is shown a modification for releasing and fixing the disks (Z (Z from and to the casings e c. A block (1 having a pin with a coiled spring is attached to casing e and a lever r, having an extension at one end through which the said pin passes, carries'a pin 0 to pass through the casing 0 into the indentations d on the disks (Z, so that when it is necessary to change the di rection of travel, the pin 0 is raised up from the indentations into which it is engaged and is swung round by means of the lever 1" into an indentation on the other disk.

The apparatus operates in the following manner: The Archimedean screw being in position in the casing and hollow shaft, in order to impart a forward motion to the boat the screw in the first casing is turned to fix the disk to the casing so that both travel together, the other disk being released by the raising of the other screw, the Archimedean screw is then pushed home and no motion is given until it is pulled forward, this action causing the short notched tube in the first casing to be drawn into contact with the teeth on the disk, revolving both it and the hollow shaft carrying the fly-wheel and the propeller by reason of the central perforation of the short tube coinciding with the groove in the Archimedean screw, the fly-wheel carrying on the motion during the return of the Archimedean screw, and so on while a continuous forward motion is required. When it is re- 5 quired to reverse the motion the reverse proceeding is adopted, the first disk is put out of gear, and the second into operation, the consequence being that the second short tube is brought into contact with the second disk and the whole is operated in the reverse direction by the reverse groove on the Archimedean screw coming into action.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In an apparatus for operating propel-' lers for boats and the like,the combination of a hollow shaft and casings with a flywheel and screw propeller attached, an

fitrehimedean screw with a double groove working freely in said hollow shaft and "operating same by means of disks with V toothed extensions, and short tubes toothed at one end in opposite directions to each other, to engage with the aforesaid toothed extensions, and capped at the other end,

with central perforations shaped to correspend with the grooves on said Archimedean screw, said dlsks and short tubes contained 1n aforesaid casings, means for throwing the disks and short tubes in or out of Gopie's or this patent may be obtained for gear as required consisting of a spring governed lever and pin engaging in indentations on. the disks, constructed and operated substantially as described and illustrated in the accompanying drawing s.. v

2. In an apparatus for operating propellers for boats and the like, the combinertion of a hollow shaft and easing with a' flywheel and screw propeller attached, an Arohimedean screw with a groove working freely in said hollow shaft and. operating groove on the Archimedean screw, said disk and short tube contained in the aforesaid casing, constructed and operated substan-.

tially as described. and illustrated in the accompanying drawings;
